ABSTRACT:
In a description area means of an image printing apparatus such as a laser printer, a request signal for setting a description area is output from the laser printer to a host apparatus and a signal for setting the description area is received by the laser printer and a necessary description area is set voluntarily. The description area is a right blank, a left blank, an upper blank and a lower blank etc. The necessary description area is set according to the description area setting signal. The necessary description area can be set voluntarily from the host apparatus, and it is unnecessary to transmit the image information as to the area excluding the setting necessary image area. During the printing operation the printing is inhibited at the description area excluding the setting description area. A protection function about an inferior description at the blank area (non-description area) in the laser printer can be obtained.
